Please do not email me asking me if ______ wheel will fit your car. The information is right here in this thread and in this forum.

Please people, do not just quote random specs- offset is directly related to rim width- you can certainly use a +55 6.5" wide rim on most late model Subarus, but you cannot use a +55 8" wide rim! Offset Nirvana is within a few millimeters of:

Lower numbers than these specs causes the tire to be farther from the center of the vehicle. This can not only cause rubbing on the upper fender well but also in the inside "splash guard" area, so rolling will not help all the problems.

Higher numbers will result in it being closer to the struts, which most often will cause rubbing on the spring perch and possibly the inner fender wheels on the front wheels.

Most often you will see wheels with oh so close offset, these are usually VW wheels remarketed for subaru owners who dont know any better.

"offset is directly related to rim width- you can certainly use a +55 6.5" wide rim, but you cannot use a +55 8" wide rim!"

Just a suggestion: this isn't necessarily true for any other car but the Impreza/WRX. This is a Subaru site as much as a WRX site. I think it's important to be as explicit as possible for a thread that's going to end up in the FAQ.

I'm just worried that people might be confused by such a general statement.

You make a good point . The optimal sizes never change, but the sedan is indeed more forgiving due to the fender flares. What I guess I'm saying is, just because the wheels fit, doesn't mean they are correct for the car .

I'm still interested to see a response to BOFslime's post. Not only is OZ's info contradictory to the FAQ above, but it seems the offset goes in the opposite direction according to OZ (17x7 offset 48 and 18x8 offset 51). .....vs.:

7.0" ....... +50 to +53
8.0" ....... +43 to +47

I'm confused. Does Subaru provide this info or are there other sources to compare to?

My car came stock from SOA with BBS RK'S they are stamped "ET48" and they are 17x7. I wrecked one in an accident and just purchased a used one on the club here,it was originaly from the tire rack. Someone told me they were different,Subaru vs tire rack's yet all the markings are the exact same. Should I be concerned? HOpe someone can answer this for me,thanks,CHRIS.....

I'm going to sit down at some point in the near future and "do the math" on the exact figures, but these are very close to correct. People with +48 7" rims are fine- it's very close to +50 . SlammedWRX, that +33 wheel is a perfect example of a wheel that someone 'got to fit' that is not correct for the car- not correct by a whole lot. The centerline of that wheel is drastically off from where Subaru intended, and if your buddy has wheel bearing or axle troubles, tell him to expect that the problems will not be warrantied . I'll say it again, because people really need to understand this...

Anything within sighting distance of these ranges is happiness for your wheel bearings.

I don't mean to pick on you specifically, I just wish people would read threads completely before replying . I've been guilty of it myself too- things go alot more smoothly when information doesn't have to be repeated .

In terms of wagon fitment. It's mostly in the tires, not in the wheels.

ok using this as a guideline:
6.5" ....... +53 to +55
7.0" ....... +50 to +53
7.5" ....... +47 to +50
8.0" ....... +43 to +47

(thanks for the info by the way, it really helps)

I really want to buy the black racing pro n-1's,
however the closest wheel i can find that would fit into this table is 18"x7.5 with +45mm offset. its
2mm off, is that still too much?
is +47 absolutly the lowest you can go with a 7.5" wheel?
